Looking for options to terminate sump pump line

I currently have 1.5 " pvc from the sump pump to outside my house. I want to bury my lines, but afraid they will freeze. I plan on going from 1.5" to 4" PVC with a 2" air gap in between them. My main problem is I'm not sure where to terminate the line. I live in a corner lot so my options are limited. I thought about running a 4" line underground the using a pop up emitter to the street. Will the pump have enough pressure to use the pop up emitter?

You would probably have to look at a pump curve for your pump to be sure.

For example : We used a de-watering pump for a yard fountain/river/stream system that the H/O wanted custom built. We used a small pump with a 1.5" outlet and it pumped a decent amount of water, but they weren't happy with the amount of water that flowed off of the rock in the fountain, so they asked for a bigger pump. We put in a bigger pump (same 1.5" line in the ground) and actually less water came off of the rock. Depending on the design of the particular pump it may perform poorly with a smaller discharge line (ie : your popup emitter which would act as a restriction)

Especially since dewatering pumps are not really designed to be pressure builders, they are more like pressure overcomers. (if that makes any sense)
